To aZZ whom it 'may concern: y

Be it known that; I, EDWARD BALBAema citizen of the United States, 'residing at Springiielal, in the count);r of Clark and State of Ohio, have invented certain' new and useful Improvements in Electrical Signals, loivhich the following a speeieatien. l

My invention relates to improvements V1n electric signals, and more particularly to a signal especiallf adapted for use on automobiles toinclieate the course the driver in.4 tends to take or his intention to stop or bach 'or any other information it may Abe found desirable to convey.

The object of my invention is to provide a signal of the character referred to which will be simple in construction and effective The sproekets or and in operation and also oneV Wliiehcan be easily anti readily manipulated byl the driver.

In 'the accompanying iirawings- Figure l is a verticai'section on the line l-1 of Fi. ,3. il.,

- Fig. 2 is e front eleratio l' Fig. 3 is a siile'view of one of the operating drums.

Fig. l is a diagrammatic view 'of the elec-trio circuits, i Referring to the drawings, A represents; a 'easing which l employ to inclose the sig?l Daling-g devices which in the present rase is,l shoni'f'provifled with lugs, a, by ineens of which it may be attached to any suitable point of support. The forwerrl side o the casing isrineloserl by a remove-ble eener B `Whieh is seem-ed thereto in anyA suitable Way, and this cover' is provided. with en opening 5, over which is seeureflfsv plate C of glass or other transparent material; thel`l plate C being secured in position by a retainer V.

The main operating flevice for the signals consists of a multiple or sectional solenoid, located et one side of the main casing which may be provided with an ol`-set portion or extension a? having a. removable oever as for the purpose; the respective sections of this solenoid being in the present cese live in number indicated by D1, D2, DE lt anfl D5. The eers E of this soenoifl hss nach end connected to a sprocket chain which passes about the sprockes Gr, G1, G2 and 13, thus forming an enflless operating device.

f' G1" jonrnaled on pins or stuos El' and li/ll seizures to the Walls of the casing A, and one of the studs, such as M, preferably has means (not shown) for adjustment to give proper tension to the cham. Shafts L and L1 extend transversely across the casing A near the top and bottom thereof, respectively', being journaled in the adjustable bearings N which are inserted from the outside of the casing A. Upon the upper shaft Lis secured a drum H and loosely mounted upon the lower shaft is a second cli-um H1, this flrum H1, however, being revoluble with said shaft L1 through the medium 'of a coil spring P for `the purpose 'hereinafter explained. The

sprocket G is connected `to the upper shaft L, and theV sprocket G3 is connected to the lower shaft L1, so that these sprockets will impart rotary movement'to the shafts when the solenoid is energized. The spiral spring P before referred' to has one of its ends con i nectedto the drum H1 by the pin R, the other enclr of the spring .being fastened to a collar lill which is secured to the shaft L1 by the pin Q; the collar being secureil to the shaftby the set-screw S so that the tension of the spring may be adjusted for the purpose of maintaining the signal ribbon or tape 0 taut, this ribbon heilig wound upon and secured to the respective drums; the tendency oi the spring la .reflect-or J and supported from the easing A by a bracket K; this lamp extending to a point infimediatel;lv behind the ribbonv O- and in line withthe openingb.

Referring' to Fig. al.. T represents a battery and l and 2 conductors leading from its terminals, Ythe conductor l being oonnected to eachof the solenoid sections and also to one terminal of the lamp, While the Y P being to reflvolse the drum Irl' about the shaft L1, the

conductor 2 leads to a movable switch mernbei' U. Associated with this switch niembor is a series oi Contacts, one for each solenoid section, the contacts being' connected with their corresponding sections by the contact is closed and thus causetlie desired Wires 3, e, 5, 6, and 7 Tlie movable switch 'member is also designed to close the lamp circuitthrough the wire `8 which leads 'to the other terminal of the lamp.

When in normal position thecore E will be in central position with respect to. the section D1 and the signal Fore `will be displayed. If the switch member` U is moved to the first Contact, or the contacty which is associated with the' section Dl of the solenoid, vthat section is energized but the core E will remain in its normal position. If the switch lever is now moved to the neXt contact, the one designated by D2, that section willibe energized and' D1 y deenergized, causing the coi-e to center itself 'with respect to the section D sofasto display the signal Stop tacts, the core will be caused to center itself with respect to the solenoid'section whose signal` to be displayed It should be -eX- plained that the contact points are so spaced that the switch member U cannot leave one contact point before engaging the next point so as to give a uniform movement to the core. To bring the signal ribbon back to its normal position, it is only necessary to reverse the operation by throwi the movable switch back to its normal position! `It will also be noted that so 'soon as the l. In an electric signaling device, a main easing, a sectional solenoid having a *core movable in either direction from one section to anotlicrby the energization ofi'said sections. a flexible ribbon having a series of signals thereon, rotatable d'iuinsto which by said solenoid will rotate viss said ribbon is connected, and flexible con` ncetions/ between the respecthfe drums and the ends of' the core of said solenoid wheresaid drums in either direction.
